Original Equipment Manufacturers (OEM) specify the amount of torque that is applied to fasteners to ensure they maintain the proper load within operating conditions. A fastener that is stretched or preloaded to its designed level of residual stress will resist failure for the given cycle load and the maximum number of fatigue cycles. It will also provide maximum resistance to loosening from vibration.
A fastener installed in an under-stressed condition will loosen under load and ultimately fail by loss of clamping force. A fastener that is over tightened will fail during installation or fail prematurely during under cycle stress.
